How to add wire through wakeboard tower

[vxooxv]

Have an Aerial tower. Now that the 650- RGB's are about to arrive for the twin bullets what the heck is the best way to get yet another set of wires down?? The installed harness has 8 wires which are all being used by the 4 speakers.

Install an identicle harness on the opposite side?

Since I believe I can hook all the RGB wires together inside the tower... Maybe - all I really think I need is essentially 1 sheilded wire so I was thinking of trying to drill holes much like the existing harness close to the existing holes maybe and use a rubber grommet of sorts I can plug the drilled hole and feed the smaller wire through??

Between the battery relocation,switch, ACR, 3 amps, new speakers I may be in over my head.

You can attach the wires to the end of the existing ones and pull them through.
Or, pull a string through that way and then attach two sets of wires since you are adding and then pull it back down.

I haven't had that much luck doing this on my tower but finally got everything except my light for top of the tower. Can't seem to run those wires through!

Also, i really like that metal grommet you got for going into the boat. Any ideas where i could get one?

It's Aerials wakeboard tower wiring harness that has 8 wires in it. My issue is - I need more wires... Probably have to do the same thing on the other side
